I'm currently not using my scoot because it's winter and freaking freezing here! (30 degrees below windchill tomorrow) but I have been back on scootdawg lately and never got opinions on this problem. Acceleration from 0 to around 15 to 20 is great but when I hit around 25 it takes quite a bit of time for it to accelerate after that. I was wondering if a 1K torque spring would help with this problem. If not what would help? Please respond soon. Thanks.

What are your rpms when you hit the point it slows? Do they stay about steady when its going from 25-30 or so or does it slowly rise?

I don't have a tach on my moped, so I don't know.

Hmm... that makes it hard to use my methods... hope someone else has an idea of what it could be

It's normal on smaller scooters.
Try putting lighter rollers in the variator. it'll help taking the most out of your engine.
On mine, I get good acceleration from 0-23MPH, slow upto 35MPH, then faster again to 48MPH.
Especially in the winter you may get these values.
Make sure you fuel regular fuel, not premium (93 oct) fuels;
also change the engine oil in the spring and autumn. In the autumn with winter coming up, have 10W30, or even 5W30 in your scoot.
In the summer use 5W40, or 10W40 in it.
Also check your tire pressure. When it's really cold, tire pressure goes down, and you may feel that the scoot acts more sluggish.
Make sure the tires have 35PSI in them (or more, if the tires allow these pressures).

I already have 6g sliders in. Also, I thought you were supposed to use 93 octane all the time. It's what is recommended in my manual and I have a bbk so people told me to make sure that I use premium. Also, my manual says to use 15w-40 which I do. BTW I am not riding it in the winter, I have it in storage in my garage.

Even the bbks don't really require premium, the compression just isn't high enough to cause a knock (typically)
Premium actually made my scoot sluggish! Honestly do a few tests one day, it wont harm anything, try some premium from the best store then try some low octane then some low octane from the worst store you can find.... I found the "lesser fuel" worked the best BUT I still use quick trip fuel for normal day runs

OK. Also, when my scoot is cold (as in first start of the day or so) and I accelerate, it sounds like I am peeling out like crazy even though I'm not. When it makes this noise it also accelerates slower. After riding for about 10-15 minutes it goes away and doesn't make the noise until another cold start. I was wondering if the belt is slipping at first and after it heats up enough it expands and stops slipping? Wouldn't a stronger torque spring help this?

try a stronger spring and a new good quality belt, it also takes more fuel for your scoot to run right when its cold. I run the 1.5k spring and love it and will use it in all my scoots holds rpms up longer and does better for acceleration and hill climbing, but you would need heavier weights and a good belt.

When it is COLD like that it probably is the BELT in the VARIATOR that is slipping NOT between the CLUTCH pulleys. Once it heats up then the BELT grabs better between the VARIATOR. Don't forget you have the CLUTCH pulley putting pressure on the belt but only the weights on the Variator. So putting on stronger contra spring will make it even worse when it is cold.

I was thinking of getting 7g rollers to try out along with a 1k or 1.5k torque spring? Which would you choose? Would I have to add 1.5k clutch springs too?
|

Post by millsc on Jan 31, 2013 21:35:07 GMT -5
i kept my clutch springs stock it seems the 1.5k spring is about two grams difference with weights from stock so if you run 6 grams now you'll need 8 grams.

So I won't loose any acceleration from adding 2g since I am upgrading the torque spring right?

correct i gained

Did you gain top end speed too?
|

Post by millsc on Feb 1, 2013 0:09:02 GMT -5
top end increased but probably from it breaking in though, the rpms just stayed up and it keeps the speed constant.

Sounds good. When spring comes around I will probably buy a 1.5k torque spring and 8g sliders. BTW how long does it take for a bbk to break in? I have around 350 miles on mine before I put it in storage for the winter. Will I notice any big difference in torque or speed if it isn't broken in already?

Mine seemed to come alive after i put 500 miles on it, may depend how you drive it.

i agree with the 1500 contra spring brilliant if you have a few hills to climb

You can try a softer belt for the winter. A non-kevlar one that is stickier on the sides. You can also try some belt dressing, but that could be a bit dangerous if you get it places it shouldn't go. It definitely is the belt slipping in the cold weather, that's why it screeches. It has little to do with the gearing ratio so a contra spring won't really help, and neither will lighter rollers. The problem is friction.

Stand back and look at the CVT and think for a minute how the CVT works, and which puts a lot of pressure on the belt and which would slip due that happening.

By cold start I mean first start of the day in the summer. I have my scooter in my garage winterized right now. So cold weather I don't think is the problem.

By the way. The noise when accelerating when the scoot is cold started after I installed the bbk.

the spring is worth it clean the clutch real good when you get it off

Can you explain what putting on a stronger contra spring does for you, by the way this is a test. So that someone asking about putting in stronger Contra springs know what it will and or will not do.

I have the same issue. I can only tote my front tire to about 15mph then its sluggish to 60mph. I think we need to look into aftermarket main springs(1500rpm).

Take a video of you toteing that front tire otherwise it didn't happen. Lots of bragging from a lot of folks about speeds and all kinds of unrealistic things. I have asked many to prove it with a Video or whatever but NONE and I MEAN NONE have YET to come back with any prove lots of excuses is all that is heard. As they say in Missouri SHOW ME.
